RL IC device. Integrated Clock Circuit Previous generations of FTDIs USB UART devices required an external crystal or ceramic resonator. The clock circuit has now been integrated onto the device meaning that no crystal or ceramic resonator is required. However, if preferred, an external 1. MHz crystal can be used as the clock source. Integrated EEPROM Previous generations of FTDIs USB UART devices required an external EEPROM if the device were to use USB Vendor ID VID, Product ID PID, serial number and product description strings other than the default values in the device itself. This external EEPROM has now been integrated onto the FT2. R chip meaning that all designs have the option to change the product description strings. A user area of the internal EEPROM is available for storing additional data. The internal EEPROM is programmable in circuit, over USB without any additional voltage requirement. Preprogrammed EEPROM The FT2. R is supplied with its internal EEPROM pre programmed with a serial number which is unique to each individual device. This, in most cases, will remove the need to program the device EEPROM. Integrated USB Resistors Previous generations of FTDIs USB UART devices required two external series resistors on the USBDP and USBDM lines, and a 1. USBDP. These three resistors have now been integrated onto the device. Integrated AVCC Filtering Previous generations of FTDIs USB UART devices had a separate AVCC pin the supply to the internal PLL. This pin required an external R C filter. The separate AVCC pin is now connected internally to VCC, and the filter has now been integrated onto the chip. Less External Components Integration of the crystal, EEPROM, USB resistors, and AVCC filter will substantially reduce the bill of materials cost for USB interface designs using the FT2.

Configurable CBUS IO Pin Options There are now 5 configurable Control Bus CBUS lines. Options are TXDEN transmit enable for RS4. PWREN Power control for high power, bus powered designs, TXLED for pulsing an LED upon transmission of data, RXLED for pulsing an LED upon receiving data, TX RXLED which will pulse an LED upon transmission OR reception of data, SLEEP indicates that the device going into USB suspend mode, CLK4. CLK2. 4 CLK1. 2 CLK6 4. MHz, 2. 4MHz,1. 2MHz, and 6. MHz clock output signal options. There is also the option to bring out bit bang mode read and write strobes see below. The CBUS lines can be configured with any one of these output options by setting bits in the internal EEPROM. The device is supplied with the most commonly used pin definitions pre programmed see Section 9 for details. Enhanced Asynchronous Bit Bang Mode with RD and WR Strobes The FT2. R supports FTDIs BM chip bit bang mode. In bit bang mode, the eight UART lines can be switched from the regular interface mode to an 8 bit general purpose IO port. Data packets can be sent to the device and they will be sequentially sent to the interface at a rate controlled by an internal timer equivalent to the baud rate prescaler. With the FT2. 32. R device this mode has been enhanced so that the internal RD and WR strobes are now brought out of the device which can be used to allow external logic to be clocked by accesses to the bit bang IO bus. This option will be described more fully in a separate application note. Synchronous Bit Bang Mode Synchronous bit bang mode differs from asynchronous bit bang mode in that the interface pins are only read when the device is written to. Thus making it easier for the controlling program to measure the response to an output stimulus as the data returned is synchronous to the output data. The feature was previously seen in FTDIs FT2. C device. This option will be described more fully in a separate application note. CBUS Bit Bang Mode This mode allows four of the CBUS pins to be individually configured as GPIO pins, similar to Asynchronous bit bang mode. It is possible to use this mode while the UART interface is being used, thus providing up to four general purpose IO pins which are available during normal operation. An application note describing this feature is available separately from www. Lower Supply Voltage Previous generations of the chip required 5. V supply on the VCC pin. The FT2. 32. R will work with a VCC supply in the range 3. V to 5. 2. 5V. Bus powered designs would still take their supply from the 5. V on the USB bus, but for self powered designs where only 3. V is available and there is no 5. V supply there is no longer any need for an additional external regulator. Integrated Level Converter on UART Interface and Control Signals VCCIO pin supply can be from 1. V to 5. V. Connecting the VCCIO pin to 1. V, 2. 8. V, or 3. V allows the device to directly interface to 1. V, 2. 8. V or 3. 3. V and other logic families without the need for external level converter I. C. devices. 5. V 3. V 2. 8. V 1. 8.

This Instructable will show you how to set up a really basic digital to analog converter so you can sta. R provides true CMOS Drive Outputs and TTL level Inputs. Integrated Power On Reset POR Circuit The device incorporates an internal POR function. A RESET pin is available in order to allow external logic to reset the FT2. R where required. However, for many applications the RESET pin can be left unconnected, or pulled up to VCCIO. Lower Operating and Suspend Current The device operating supply current has been further reduced to 1. A, and the suspend current has been reduced to around 7. A. This allows greater margin for peripheral designs to meet the USB suspend current limit of 5. A. Low USB Bandwidth Consumption The operation of the USB interface to the FT2. R has been designed to use as little as possible of the total USB bandwidth available from the USB host controller.

Low USB Bandwidth Consumption The operation of the USB interface to the FT2. R has been designed to use as little as possible of the total USB bandwidth available from the USB host controller. Power Management Control for USB Bus Powered, High Current Designs The PWREN signal can be used to directly drive a transistor or P Channel MOSFET in applications where power switching of external circuitry is required. An option in the internal EEPROM makes the device gently pull down on its UART interface lines when the power is shut off PWREN is high. In this mode any residual voltage on external circuitry is bled to GND when power is removed, thus ensuring that external circuitry controlled by PWREN resets reliably when power is restored. UART Pin Signal Inversion The sense of each of the eight UART signals can be individually inverted by setting options in the internal EEPROM. Thus, CTS active low can be changed to CTS active high, or TXD can be changed to TXD. FTDIChip ID Each FT2. R is assigned a unique number which is burnt into the device at manufacture. This ID number cannot be reprogrammed by product manufacturers or end users. This allows the possibility of using FT2. R based dongles for software licensing. Further to this, a renewable license scheme can be implemented based on the FTDIChip ID number when encrypted with other information. This encrypted number can be stored in the user area of the FT2. R internal EEPROM, and can be decrypted, then compared with the protected FTDIChip ID to verify that a license is valid. Arduino Playground I2. CEEPROMI got my hands on an AT2. C2. 56 2. 56 kbit 3.
